GOLD-PAN.

SPECIFICATION forming part of Letters Patent No. 663,296, dated December 4, 1900.

Application led January 20, 1900. Serial No. 2,207. (No model.)

To fl/ZZ whom it may concern:

Beit known that I, DANIEL B. N nwKIRK, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Gold-Pans, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has particular reference to a 1o centrifugal gold-pan; and it consists in the novel formation of a pan of this type whereby the collection of the gold by the panning process may be more quickly and readily effected.

The invention further consists inthe peculiar construction and arrangement of the varions parts of the gold-pan, as will be more fully hereinafter set forth, and pointed out in the claims.

2o Figure 1 is a perspective view of my improved gold-pan in readiness for use, and Fig. 2 is a vertical central section therethrough.

The reference-letter A designates the pan proper, which is preferably conical in configuration and terminates at its apex in a socket-piece B, secured to the pan-body by means of rivets d.

C designates an upright or standard secured -to and extending centrally from the pan,

3o which standard has a tubular end portion D,

adapted to engage over a pin or stud E, mounted upon a base-section F. A preferable manner of attaching the standard or upright to the pan consists in forming a tubular bear-' ing G for the socket depending centrally therefrom and securing the lower end of the standard within said bearing, the parts being held together by corresponding screw-threads formed, respectively, upon the exterior of the standard and the interior of the bearing G, as plainly shown in Fig. 2. The base-section above referred to preferably consists of the base proper, comprising the cross-pieces H and I, suitably secured to each other at their centers, and the circular plate J, attached in any suitable manner to the base and carrying the pin E, before described.

The reference-letter K designates a tubular member adapted to be sleeved over the standard and to rest at its lower end upon the inner portion of the pan-socket.

L is an operating-handle secured to the mem` ber referred to, and M designates a stirrer mechanism carried by the tubular member at its lower end. In construction the stirrer devices comprise, essentially, stirrer-blades b c, Fig. l, secured at their inner ends to the member referred to and bent to conform substantially to the coniiguration'of the pan.

Gland@ representsimilarstirrer-blades sub- 6o stantially L-shaped in form, which extend downwardly into the socket B in proximity to the bottom of the latter.

The upper or free end of the standard or upright O is provided with a squared end O, and P designates a link pivotally connected at one end with thea-rm L and having a recess or aperture Q formed in its opposite or free end, conforming in configuration to and adapted to engage over the squared end O. 7o

The particular construction of my invention having been thus set, forth the manner ot' operation is as follows: The structure, as shown in Fig. l, is placed upon the bed of the stream at such a depth as to permit of the A pan proper being entirely submerged,the link being normally out of engagement with the standard. The pan proper is lled with the material from which the gold is to be eX- tracted, and the operator by means of the han- 8o dle L rotates the blades referred to, thus separating the gold, which falls to the bottom of the pan and is collected in the socket. To remove the foreign material from the pan, the link is thrown into engagement with the standard, thus locking the handle to the pau, and the centrifugal motion imparted to the latter produces the result desired.

From the foregoing description of my invention it will be seen that the rotation of 9o the pan and stirring of the pan contents is effected by means of a single operating device which simplifies the construction of the goldpan,and in consequence lessens the cost of its manufacture; also, by employing a base-section, such as I have described, the rotation of the pan is more easily accomplished.

While I have shown and described a certain type of stirrer mechanism and an operating device for the same, I do not desire to roo be limited to this particular style, as other forms could be used without departing from dependent rotary movement, stirrer mechan.- `l

ism carried by the tubular member,an operating deviee for rotating saidtnbular n1 embei independently of the pan, and means fonloek ing the operating device to the pan, whereby thelatten may be rotated after thestirring hasbeen effected.
